Apache Ignite 2.16容器缺jmap/jstack，负载下Pod堆异常求助

环境与现象 #

• Kubernetes环境中部署3个副本的Apache Ignite 2.16 Pod
• 负载测试期间，Ignite Pod出现重启现象，堆内存持续攀升后出现异常变化，相关监控数据如下：

额外配置信息 #

• 未开启onHeapEnabled，配置值为False
• 未启用Native persistence
• 测试时段未触发SQLIgnite查询

排查诉求 #

尝试抓取堆转储（Heap dump）和线程转储（Thread dump）时，发现Apache Ignite Docker镜像中缺少jmap、jstack命令，请求告知解决方案，或推荐内置这些命令的JDK11版Apache Ignite Docker镜像。
